Application filed Septemberfi'th 192G. SerialNo. 137,903.

.his invention relates to vehicle bumpers and more particularly to a bumper for attachment to automobiles An important object of the invention is to provide a device of this character which has the necessary strength and which, at the same time,'has not too great a' weight and may be inexpensively produced.

A further object of the invention is to proyide a device of the character which may be readily attached and which has employed in its construction a minimum number of parts all formed of the same material. a A still further object of my invention is to provide avehicle bumper bar that-is made] of one piece, that may be stamped or pressed from abar of cold rolled steel, and that will have a groove extending for the full length. and yet will provide a bumper surface of proper width.

A further object is to provide a bumper bar having a smooth bumper surface with no attaching means smooth bumper surface.

A still further object of my invention is to provides. bumper bar constructed of a single integral unitary structure.

.These and other objects I attain by the construction shown in the accompanying drawings,.in which the same reference characters indicate the saine parts in all of the views:

. Figure 1 is a top view of the bumper.

Figure2 is a view in front elevation of the bumper.

Figure 3 is a view taken on the line 3- 3 of Figure 1 looking in the direction ofthe arrows, and showing particularly the chanp nel section and the integral wings formed therewith.

Figure t is a fragmentary perspective view of the bumper.

'Referring now 'more particularly to the drawings, the front or bumper bar 1Q con- .sists of a central portion or base 11 having side flanges 12 and 13 extending at rig-ht angles forwardly therefrom, thereby forming a channel section- Wings 14 and 15' reangles forwardly from the flanges and inaparallelism -to the central portion 11. The bar 10 curves slightly to the rear, as shown at .16 and 17 respectively, and the central portion 11 has a hole 18 at the middle thereofand holes 19 and 20% about the middle or the central portion,

projecting beyond the v be modified in certain "tion of said chant the curved end sections, and throu h thesecholes bolts 21 are passed and fastene in this instance comprising a semi-elliptical spring 23 which is attached to the vehicle by any convenient conventional means, wellknown in the art. It will be noted that the formed by the flanges and the Wings, which wings thereby present a smooth protecting bumper surface of sub stantial strength and width, and further that flanges and wings are all of substantially the same thickness. As is obvious from the drawing, ton or groove extends the entirelength of the bumper, and the the channel secy by means of nuts 22, toa supporting means, the supporting meansbumper may be 0011- f structed of any suitable-material, although the preferred material will 'be' cold rolled steel, and may appropriate width and'thickness.

It will be obvious that the general structure hereinbefore set forth must necessarily v particulars to permit its attachment to various types of cars and accordingly do not limit myself to such spebe made from a single bar of I so' cific structureex'ceptas hereinafter claimed.

Having thus described my invention, what I claim is 1- v 1. An integrally formed automobile bumper. bar, comprising a flat elongated projecting wing on in the same horizontal directionas said wing, a second wing extending on theupper portion of said channeled section and in the same plane as said first wing, as and for the urpose set forth.

2. An integrally bar, comprising a flat wing on the v neled'section'centrally located and extending in the same horizontal a second wing extepding on the upper poreled section and in the same lane as said first wing. resilient means bolted to said channeled section for holding said bumper in its fixed position, as and for thepurpose set forth;

formed automobile bumper elongated pro ectmg 3. A vehicle bumper bar consisting of an integral bar, said bar comprising a central ortion, an upper and a lower flange extend,- ing at substantially right ar ies forwardly therefrom, each flange having a wing extending at ri ht angles therefrom and in the lower portion thereof, a chan-' neled section centrally locatedand extending lower portion thereof, a chan-- direction as said wing,

ill)

parallelism with the central portion, said central portion, flanges and wings all being of the same thickness.

"4. An inte ral vehicle bumper bar consisting of a c iannel section and wings, said channel section extending the full length of the, hamper, the greater part of the bumper bar being substantially straight and the end section's being slightly curved toward the rear, the channel section consisting of a central portion and flanges extending at right angles forwardly therefrom, and the Wings extending at right angles from the fiangesand parallel to the central portion.

'5..An integral vehicle bumper bar consisting 0% a channel section and wings, said channel section extending the full length of the bumper, the greater part of the bumper bar being substantially straight and the end sections being slightly curved toward the rear, the channel section consisting of a contral portion and flanges extending at right angles forwardly therefrom, and the wings extending at right angles from the flanges and parallel to the central portion, said cen tral portion, flanges and wings being of substantially the same thickness. 7

6. An integral vehicle bumper bar conslsting'ot a channel section and. wings, said channel section extending the full length of the bumper, the greater part of the bumper bar being substantially straight and the end sections being slightly curved toward the rear, the channel section consisting of a central portion andflanges extending at right angles forwardly therefrom, and the wings extending at right angles from the flanges and parallel to the central portion, there being a bolt-hole at the middle of said central portion and one in the middle 'of each of the curved ends of said portion.

7. An integral vehicle bumper bar consisting of a channel section and. wings, said channel section extending the full length of the bumper. the greater part of the bumper being substantially straight and the end sections being slightly curved toward the rear, the channel section consisting of a cen tral portion and flanges extending at right angles forwardlytherefrom, and the Wings extending at right angles from the flanges and parallel to the central portion, support" gles forwardly therefrom, and the wings extending at right angles from the flanges and parallel to the central portion, said cen 'tral portion; flanges and wings being of substantially t io same thickness, supporting means for said bumper, fastening means for attaching the bumper to said supporting means. whereby the fastening means is pro tected by the channel section.

In testimony whereof I hereby affix my signature.
